You could do a 5 (or 10 or whatever) reasons that I love being a DVC member... (I think I'm going to steal my own suggestion, hahaha).
And list them out with some photos of the property, the Welcome Home sign, a scan of your membership card, a scan of your deed/paperwork...
Reason -- 1)discounted APs, 2) Laundry facilities!!, 3) THE JACUZZI TUB!!!, 4) The CMs saying "Welcome Home", etc.... (well, those are mine anyway)
